SpringBoot+jpa+hibernate

有一个查询语句 select * from 表1 WHERE name = #{request.name} <![CDATA[ AND age >= #{minAge} AND age <= #{maxAge} ]]> <![CDATA[ AND weight >= #{minWeight} AND latitude <= #{maxWeight} ]]> 这样一个查询语句，如何转换成使用SpringBoot+jpa+Hibernate方式的查询呢？

springboot JPA保存报错

springboot jpa继承问题，谢谢解答。

``` @Entity(name = "Account") @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public static class Account { @Id private Long id; private String owner; private BigDecimal balance; private BigDecimal interestRate; } @Entity(name = "DebitAccount") public static class DebitAccount extends Account { private BigDecimal overdraftFee; } ``` 最终在数据库中生成了Account表，DebitAccount表，能否不生成Account表，只要DebitAccount表，谢谢各位帮忙

springboot 配置hibernate 开始使用的是mysql，都正常，但是换成Oracle后总是创建表。

springboot 配置hibernate 开始使用的是mysql，都正常，但是换成Oracle后总是创建表。所以后台报如下表重复错误。这是为什么呀？应该是如果发现表已经有的话不应该再创建才对，请帮我看下哪里配置错了。 再详细说明下我的场景： 数据库映射的对象Product。 第一次系统启动肯定会创建一个，因为数据库中是没有这个表，然后系统重启或者再次启动，正常来讲，Product对象没有改过，数据库表也存在，hibernate不应该再创建，但是目前就是再创建，所以报表名已经有的错误。 ``` Caused by: java.sql.SQLSyntaxErrorException: ORA-00955: 名称已由现有对象使用 at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:447) ~[ojdbc-6.6.0.jar:11.2.0.4.0] at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:396) ~[ojdbc-6.6.0.jar:11.2.0.4.0] at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:951) ~[ojdbc-6.6.0.jar:11.2.0.4.0] ``` ``` server: port: 8001 spring: application: name: DEMO_TEST #f服务名称定义 datasource: type: com.alibaba.druid.pool.DruidDataSource # 当前数据源操作类型 #driver-class-name: com.mysql.cj.jdbc.Driver # mysql驱动包 driver-class-name: oracle.jdbc.driver.OracleDriver #url: jdbc:mysql://127.0.0.1:3306/rd_plm?serverTimezone=GMT%2B8 # 数据库名称 url: jdbc:oracle:thin:@127.0.0.1:1521/DD username: root password: root dbcp2: min-idle: 5 # 数据库连接池的最小维持连接数 initial-size: 5 # 初始化连接数 max-total: 5 # 最大连接数 max-wait-millis: 150 # 等待连接获取的最大超时时间 jpa: hibernate: naming: physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl ddl-auto: update show-sql: true properties: hibernate: #dialect: org.hibernate.dialect.MariaDBDialect dialect: org.hibernate.dialect.OracleDialect current_session_context_class: org.springframework.orm.hibernate5.SpringSessionContext #database: MYSQL database: oracle open-in-view: true ```

springboot JPA的多表查询只能是关系表或者用hql来查询的么?

springboot 如上,看了很多教程,对于多表查询要么是 @Query注解用hql来查询,要么就是@ManyToOne 还有其他方式么?我们数据库表是不建立关系的.

springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理 可能懒加载出现问题求大神解答

最近项目中使用springboot2.1.4 + jpa + hibernate 使用aop注解形式实现多数据源管理,用的就是网上大多数人使用的一套代码,但是我在项目中使用后发现如果配置 spring配置文件 application.yml 中open-in-view: false 跨数据源查询正常,但是保存或者修改失败原因是事务没有提交,一旦把open-in-view改成true则不能跨数据源查询,修改保存正常事务正常提交求解,具体代码如下实现 1. application.yml ``` spring: ## 数据库配置 #datasource: #driver-class-name: com.mysql.jdbc.Driver #url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 #username: root #password: 123456 #url: jdbc:mysql://127.0.0.1:3306/boot-jpa-back-sys2?useSSL=false&characterEncoding=utf-8 #username: root #password: datasource: test1: driver-class-name: com.mysql.jdbc.Driver jdbc-url: jdbc:mysql://192.168.101.125:3306/cdv?useSSL=false&characterEncoding=utf-8 username: root password: 123456 type: com.alibaba.druid.pool.DruidDataSource test2: driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc-url: jdbc:sqlserver://192.168.101.125:1433;database=Test;
